This mod synergizes well with True Steel and/or True Punishment, as the increase in critical hit chance will make it more likely for this mod to activate.

Berserker will not proc while Hysteria is active; however, it will apply the attack speed buff if you already had a Berserker proc when activating Hysteria. This makes it useful to engage in melee combat shortly before using Hysteria, so as to gain Berserker's benefits.

Prior to Update 13.8.1, Berserker would treat the melee Stealth damage bonus as a critical hit, activating or refreshing the speed bonus. However, despite the damage numbers still displaying as yellow, they are no longer counted as critical hits.
